Differentials
Front and rear bearing preload
For new bearing:
19.6 — 28.4 N (2.0 — 2.9 kgf, 4.4 — 6.4 lb)
at companion flange bolt hole
For used bearing:
8.34 — 16.67 N (0.85 — 1.7 kgf, 1.87 — 3.75 lb)
at companion flange bolt hole
Adjusting preload for front and rear bearings
NOTE:
At this time, install a pinion height adjusting shim
which is temporarily selected or the same as that
used before. Measure and record the thickness.

ST3 398507703 DUMMY COLLAR
(A) Pinion height adjusting shim
(2) Measure the clearance N between the end
of ST2 and the end surface of ST1 by using a
thickness gauge.
NOTE:
Make sure there is no clearance between the case
and ST2.

(3) Obtain the thickness of pinion height adjust-
ing shim to be inserted from the following
formula, and replace the temporarily installed
shim with this one.
REAR DIFFERENTIAL FOR T-TYPE
S3M0518B
H3M1309B
DI-32
T = To + N − (H x 0.01) − 0.20 mm (0.0079
in)
NOTE:
Use copies of this page.
T Thickness of shim temporarily
inserted mm (in)
To Thickness of pinion height adjusting
shim mm (in)
N Reading of thickness gauge mm (in)
H Figure marked on drive pinion head
Memo:
(Example of calculation)
To = 2.20 + 1.20 = 3.40 mm
N = 0.23 mm H = + 1,
T = 3.40 + 0.23 − 0.01 − 0.20 = 3.42
Result: Thickness = 3.42 mm
Therefore use the shim 383605200.
